Pennsylvania Route 315 (PA 315) is an 8.2-mile-long (13.2 km) state highway located in Luzerne County, Pennsylvania. The southern terminus is at an interchange with the PA 309 freeway and the northern terminus of PA 309 Business (PA 309 Bus.) in Wilkes-Barre. The northern terminus is at the entrance of the Wilkes-Barre/Scranton International Airport in Pittston Township just past an interchange with Interstate 81 (I-81). PA 315 heads northeast from PA 309 and PA 309 Bus. as a multilane road through suburban development in the Wyoming Valley parallel to I-81. The route comes to an interchange with I-81 and I-476 (Pennsylvania Turnpike Northeast Extension) before passing through Dupont along a one-way pair. Past here, PA 315 follows a divided highway to I-81 and the airport.

PA 315 was first designated in 1928 between PA 115 in Wilkes-Barre and U.S. Route 11 (US 11, now unnumbered Main Street) in Pittston, following Main Street between the two cities. In the 1930s, the route was moved to a multilane highway running between PA 115 east of Wilkes-Barre and US 11 in Dupont. The route was extended north along a divided highway to US 11 in Moosic in the 1950s. The northern terminus of the route was moved to I-81 near the airport in 1966, with I-81 replacing the route north of there. In the 1970s, the route begun at US 11 in Larksville and traveled through Wilkes-Barre, but was reverted by the 1980s. In the 1980s, the north end was moved to US 11 in Dupont. The south end was changed from PA 115 to an interchange with the PA 309 freeway in 1991. By 2003, PA 315's northern terminus reverted to its current location.
